Understanding Race Ratings

What "Safe," "Likely," "Lean," and "Toss-Up" actually mean—and how analysts decide which races to watch.

0:00--:--

When you look at our interactive map, you'll see races color-coded by how competitive they are. Those colors come from race ratings—assessments by nonpartisan analysts who study every competitive election in the country and assign each one a category based on how likely either party is to win.

What Are Race Ratings?

Race ratings are predictions made by political analysts about how competitive an election will be. They're not endorsements and they're not based on who the analysts want to win. They're based on data: polling, fundraising, historical voting patterns, candidate quality, national mood, and on-the-ground reporting.

Think of them like weather forecasts for elections. A "Safe Republican" rating doesn't mean Democrats can't win—it means, based on everything analysts can measure, the Republican candidate has an overwhelming advantage. Upsets happen, just like surprise storms.

The Rating Scale

Most rating systems use a seven-point scale. Here's what each level means:

Safe R

Safe Republican

The Republican candidate is expected to win by a wide margin. The opposing party isn't seriously contesting the race. Think: a deep-red district where the Republican regularly wins by 20+ points.

Likely R

Likely Republican

The Republican is favored, but conditions could shift. The opposing party has a credible candidate or the district has trended more competitive. A major national wave or scandal could make this competitive.

Lean R

Lean Republican

The Republican has a slight edge, but this is a genuinely competitive race. Polling is close, both candidates are raising real money, and the outcome could go either way with a push. These are races worth watching.

Toss-Up

Either party could win. The race is essentially a coin flip based on available data. These are the races that decide which party controls the Senate, House, or a governor's mansion. Every vote matters most here.

Lean D

Lean Democrat

The Democrat has a slight edge, but the race is competitive. Same dynamics as Lean Republican, just in the other direction.

Likely D

Likely Democrat

The Democrat is favored, but the race isn't locked up. A strong challenger, low turnout, or a national shift could make it interesting.

Safe D

Safe Democrat

The Democrat is expected to win easily. The opposing party isn't seriously competing. Think: a deep-blue urban district where the Democrat wins by 30+ points.

Who Makes These Ratings?

Several organizations publish race ratings. The most widely respected are nonpartisan—they don't endorse candidates or take sides. The Midterm Project uses ratings from two of them:

Cook Political Report

Founded in 1984 by Charlie Cook, this is considered the gold standard for race ratings. Their team of analysts rates every Senate, House, and gubernatorial race, updating throughout the cycle as conditions change. They're cited by both parties and major news outlets.

Sabato's Crystal Ball

Published by the University of Virginia Center for Politics, led by Larry Sabato. Like Cook, they rate every competitive federal and gubernatorial race. Their academic affiliation and long track record make them a trusted nonpartisan source.

Other notable rating organizations include Inside Elections (formerly Rothenberg & Gonzales) and 270toWin, which aggregates ratings from multiple sources.

How Do Analysts Decide?

Rating a race isn't just looking at one poll. Analysts weigh a combination of factors:

Partisan lean

How has this state or district voted in recent elections? A district that went +15 Republican in the last three cycles starts from a very different baseline than one that swung between parties.

Incumbency

Incumbents win re-election the vast majority of the time. An open seat (no incumbent running) is almost always more competitive than one where a sitting member is defending.

Candidate quality

Has the challenger held office before? Do they have name recognition? Are they running a professional campaign? A weak candidate in a winnable district can shift a rating toward the other party.

Fundraising

Money isn't everything, but it's a signal. A challenger raising serious money suggests a real campaign. An incumbent with a thin war chest may be vulnerable. See our Who's Running page for fundraising data.

Polling

Public and private polls give a snapshot of where voters stand. Analysts look at polling averages, not individual polls, and weight them by quality and recency.

National environment

Is the president popular or unpopular? Is one party energized? Midterms historically go against the president's party, but the size of that wave varies. A strong national tide can shift dozens of races at once.

Why Do Ratings Change?

Ratings aren't set in stone. They're updated throughout the election cycle as new information emerges. Common triggers for a rating change:

A strong or weak primary result — a candidate who barely survives a primary may enter the general election wounded
New polling data — a Toss-Up race where one candidate builds a consistent lead might shift to Lean
Fundraising reports — a surge in donations (or a collapse) signals shifting momentum
Candidate scandal or gaffe — a major controversy can move a Safe race to Likely overnight
Redistricting or legal changes — new district maps can make a previously safe seat competitive
National events — a recession, Supreme Court decision, or major policy change can shift the entire map

How Accurate Are Race Ratings?

Pretty accurate, actually. The Cook Political Report has rated thousands of races over four decades, and their final ratings correctly predict the winner the vast majority of the time—especially for races rated Safe, Likely, or Lean. The closer you get to Toss-Up, the less certain the outcome, which is the whole point of the category.

That said, ratings are not guarantees. Upsets happen. In 2022, several races rated as Likely or Lean for one party went to the other. In 2018, a "blue wave" flipped races that analysts had rated as competitive but not necessarily Democratic. The value of ratings isn't that they're always right—it's that they tell you where to pay attention.

A good rule of thumb

Safe and Likely races rarely flip. Lean races flip sometimes. Toss-Up races are where elections are won and lost. If you want to know which races will decide control of Congress, look at the Toss-Ups and the Leans.

How The Midterm Project Uses Ratings

On our interactive map, we show race ratings for every competitive Senate race. The color coding matches the scale above: deeper red or blue means safer for that party, and amber means Toss-Up.

We pull our ratings from the Cook Political Report and Sabato's Crystal Ball, updating them manually when analysts change their calls. We check for updates monthly during the primary season and more frequently as the general election approaches.

Our goal isn't to tell you who to vote for. It's to help you understand which races are competitive, where your vote has the most impact, and where to focus your attention if you want to stay informed.

Why This Matters for You

If you live in a state or district with a Toss-Up or Lean race, your vote carries outsized influence. These are the races where a few thousand votes—or even a few hundred—can determine the outcome. They're also where campaigns spend the most money, where outside groups pour in resources, and where voter turnout makes the biggest difference.

Even if you live in a Safe district, understanding race ratings helps you follow the national picture. When you hear pundits say "Democrats need to flip three seats to take the Senate," race ratings tell you which three seats they're talking about.
